A known system of deep-sea oil production, including devices for combining equipment during subsea production, RU No. 2665011 C2, ЕВВ 43/01, Е21В 43/36, 05/23/2018.

In the known system, devices similar to the claimed device are not provided.

A known design of the fixing device, made in the form of a bracket mounted on a preload object (presumably a pipe), with a central part repeating the configuration of the surface of the object, US 2012/0201607 A1, ЕВВ 43/01, F16L 1/26, 08/09/2012.

The known locking device is designed to lower or, alternatively, the subsequent extraction of the end of the pipeline, which is equipped with a connecting part for mating and connecting with the first connecting part on the seabed, the device contains a Central lifting frame, a guide part forming an extension of the lifting frame, and a lifting bracket , as well as gripping mechanisms, which, on the one hand, are actuated to partially limit and hold the end of the pipeline, and on the other hand, they can be removed to free the end of the pipeline from the lifting frame, and does not apply to the field of use of the claimed device.

The closest analogue of the design of the device of mechanical action for holding the interchangeable tool in the connection system of equipment for underwater mining was not found.

The present invention is based on the solution of a problem that allows you to create a new device with high structural qualities for holding a replacement tool with reliable operation of the equipment connection system in underwater production.

The technical result of the present invention is:

- in blocking the vertical movement of the interchangeable tool, due to the design of the device, consisting of handles, clamps and connecting rod mechanisms connecting each handle with a clamp;

- in the implementation of fixtures with structural elements of mechanical action, while automatically locking and automatically restoring their original position due to the weight of the tool itself during transportation and installation, and when removing the load from the weight of the tool, return the handles to their original position;

- in the reliable fixation of the interchangeable tool due to the extension of the clamps beyond the housing with their entry into the grooves located on the interface frame, by means of a connecting rod mechanism;

- in reducing the cost by reducing the metal consumption of the design of the device, in improving manufacturability by simplifying structural elements, in ensuring automatic mode only from mechanical interaction of components and parts in the device as a whole, as well as in improving safety and reliability in underwater mining.

According to the invention, the design of the mechanical action device is adapted to hold the interchangeable tool in the connection system of the subsea production equipment during operation. The interchangeable tool is housed in a housing with an upper bar. The equipment connection system is limited by the interface frame for fixing the interchangeable tool with the possibility of blocking its vertical movement. The pairing frame is made with grooves.

The design of the mechanical action device has at least two handles located on the upper bar, sliders are fixed at the end of each of the handles with the ability to extend upwards and lengthen the handles. The sliders have the ability to move inside the guide bushings mounted on the upper bar with the ability to move up the sliders inside them. The inner contact surfaces of the guide bushings are made with inserts of a polymeric material, rigidly fixed to the upper bar and allowing the sliders to slide.

Also, the sliders have the ability to restrict movement by means of glasses mounted on each slide and made with a compression spring. The compression spring is located between the glass and the upper bar of the housing.

Inside the housing are connecting rod mechanisms and latches. Each connecting rod mechanism consists of twin connecting rods. Each latch is fixed on an axis inside the housing for interchangeable tools.

In this case, paired connecting rods are fixed on the lower end of each slider by means of an axis and limiting bushings on one of their sides, and on their other side, paired connecting rods are fixed to the clamp by means of the axis, and the clamp by the axis and limiting bushings is fixed inside the housing, allowing rotation around the axis by twin rods and the possibility of entering the housing and / or going outside the housing when the sliders move. In addition, by means of paired connecting rods, the latch has the ability to rotate on the axis and enter the grooves of the mating frame when the compression spring automatically restores the compression position.

In addition, caprolon was used as the polymer material for the inserts of the guide bushings.

The applicant has not identified sources containing information on technical solutions identical to the present invention, which allows us to conclude that it meets the criterion of "novelty."

Due to the implementation of the distinguishing features of the invention (in conjunction with the features indicated in the restrictive part of the formula), important new properties of the object are achieved.

The constructive implementation of the device from handles, clamps of connecting rod mechanisms, structural elements of mechanical action while ensuring automatic mode only from the mechanical interaction of its components and parts allows you to create a new device with high structural qualities to hold the interchangeable tool in the equipment connection system in conditions of underwater mining.

The applicant is not aware of any publications that would contain information on the influence of the distinguishing features of the invention on the achieved technical result. In this regard, according to the applicant, it can be concluded that the claimed technical solution meets the criterion of "inventive step".

The design of the mechanical action device for holding the interchangeable tool 1 in the connection system of the equipment 4 for underwater production during operation is configured to hold the replaceable tool 1, located in the housing 2 with the upper bar 3, in the connection system of the equipment 4.

The equipment connection system 4 is limited by the interface frame 5 for fixing the interchangeable tool 1 with the possibility of blocking its vertical movement, made with grooves 6 in it.

The design of the device has at least two handles 7 located on the upper bar 3.

At the end of each of the arms 7 are fixed sliders 8 with the possibility of extension up and lengthening of the arms 7.

The sliders 8 have the ability to move inside the guide bushings 9.

Guide bushings 9 are mounted on the upper bar 3 with the possibility of upward movement of the sliders 8 inside them.

Moreover, the internal contact surfaces of the guide bushings 9 are made with inserts 10 of polymer material, rigidly fixed to the upper plate 3 and to ensure the sliding of the sliders 8.

As a polymer material for the inserts 10 of the guide bushings 9 used caprolon.

Also, the sliders 8 have the ability to restrict movement by means of cups 11 mounted on each slider 8 and made with a compression spring 12 located between the cup 11 and the upper plate 3 of the housing 2.

Inside the housing 2 are connecting rod mechanisms 13, each of which consists of paired connecting rods 14.

Inside the housing 2 are latches 15, each of which is fixed on the axis 18 inside the housing 2 for interchangeable tools 1.

At the same time, on the lower end of each slider 8, by means of the axis 16 and the limiting bushings 17, paired connecting rods 14 are fixed on one side thereof, and on their other side, paired connecting rods 14 are fixed to the latch 15 through the axis 18.

The latch 15 by means of the axis 19 and the limiting bushings 20 is fixed inside the housing 2, providing the possibility of rotation around the axis 19 by means of paired connecting rods 14 and the possibility of entering the housing 2 and / or going beyond the housing 2 when the sliders 8 move.

In addition, by means of paired connecting rods 14, the latch 15 has the ability to rotate on the axis 19 and enter the grooves 6 of the interface frame 5 when the compression spring 12 automatically restores its initial position.

Use of the device.

The adaptation of the mechanical action to hold the interchangeable tool 1 in the equipment connection system 4 ensures its fixation in the interface frame 5 of the equipment 4 connection system with the possibility of locking the replacement tool 1 from vertical movement in underwater mining.

To install the interchangeable tool 1 in the interface frame 5, it is transported by a lifting mechanism, at least for two handles 7, placed on the upper bracket 3 of the housing 2.

When lifting the interchangeable tool 1 with a lifting mechanism by the arms 7, it lengthens the arms 7 by its own weight by pushing up the slide 8 fixed to the end of each of the arms 7.

The movement of the slider 8 upward is carried out inside the guide sleeve 9, mounted on the upper plate 3 of the housing 2.

The inner contact surface of the guide sleeve 9, made with inserts 10 of a polymer material, allows the sliding of the sliders 8.

Also, the sliders 8 have the ability to restrict movement by means of glasses 11.

Given that the connecting rod mechanism 13, mounted on one side to the bottom of the slider 8 (Fig. 3), and on the other hand, using the axis 18 and fasteners, is fixed to the latch 15, which is also mounted on the axis 19 with fasteners and limiting bushings 20 inside the housing 2 (Fig. 2), which allows the latch 15 to rotate around this axis 19 by means of a connecting rod mechanism 13, to go outside the housing 2 or to enter the housing 2 when the slider 8 moves up or down, respectively.

After installing the replacement tool 1 in the pairing frame 5 and releasing the handles 7, the slider 8 due to the compression spring 12 located between the cup 11 and the upper plate 3 of the housing 2 (after removing the load from the compression springs 12 from the dead weight of the replacement tool 1) is automatically restored and takes its starting position.

In this case, by means of connecting rod mechanisms 13, the latches 15 rotate each on the axis 19 and enter the grooves 6 of the interface frame 5, being outside the housing 2. In this case, the protruding part of the retainer 15 enters the groove 6 and provides a stop for the retainer 15 in the upper wall of the groove 6, thereby automatically fixing the interchangeable tool 1 from vertical movement in the interface frame 5.

When removing the replacement tool 1 from the interface frame 5, the clips 15 are retracted into the housing 2 to prevent jamming of the replacement tool 1 by the protruding parts of the retainer 15 in the interface frame 5.

It should be borne in mind that when lifting the tool 1 with a lifting mechanism by the handles 7, the tool 1 under its own weight helps to lengthen each handle 7 by an amount L in the range of 10-100 mm, by extending upward, fixed to the end of each of the handles 7 of the slider 8, for this, the glass 11 is fixed on the slider 8 at a distance L within 10-100 mm from the upper strip 3 of the housing 2 (Fig. 4, Fig. 5).

It should be borne in mind that after installing the interchangeable tool 1 in the interface frame 5 and releasing the handles 7, the slider 8 is automatically lowered to its original position by means of the compression spring 12, while by means of the connecting rod mechanism 13, the latches 15 enter the grooves 6 of the interface frame 5, the limits of the housing 2 by a value of b within 5-35 mm (Fig. 1).

The choice of the limit of 10-100 mm for distances L, as well as the limit of 5-35 mm for the value of b are optimal and are determined by the design of the proposed device.

The claimed invention provides retention of the interchangeable tool relative to the frame pair when it is fixed in it. The constructive implementation of the device has the ability to perform fixation during mechanical movement of its elements while automatically fixing and restoring their original position.
